QA Is the New KR: Question-Answer Pairs as Knowledge Bases

no code implementations1 Jul 2022 Wenhu Chen, William W. Cohen, Michiel de Jong, Nitish Gupta, Alessandro Presta, Pat Verga, John Wieting

In this position paper, we propose a new approach to generating a type of knowledge base (KB) from text, based on question generation and entity linking.

Learning Dense Representations for Entity Retrieval

no code implementations CONLL 2019 Daniel Gillick, Sayali Kulkarni, Larry Lansing, Alessandro Presta, Jason Baldridge, Eugene Ie, Diego Garcia-Olano

We show that it is feasible to perform entity linking by training a dual encoder (two-tower) model that encodes mentions and entities in the same dense vector space, where candidate entities are retrieved by approximate nearest neighbor search.

Globally Normalized Transition-Based Neural Networks

1 code implementation ACL 2016 Daniel Andor, Chris Alberti, David Weiss, Aliaksei Severyn, Alessandro Presta, Kuzman Ganchev, Slav Petrov, Michael Collins

Our model is a simple feed-forward neural network that operates on a task-specific transition system, yet achieves comparable or better accuracies than recurrent models.
